BATH-TUB PATTERN.

SPECIFICATION forming part Of Letters Patent No. 782,776, dated February 14, 1905.

Application filed October 28 1904. Serial No, 230,288.

To (1/7], whom trim/a1 concern.-

Be it known that I, FREDERICK D. Cook, a citizen of the United States, residing at Blairsville, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Bath-Tub Patterns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in patterns for bath-tubs.

In the manufacture of bath-tubs it frequently occurs that an order is received for tubs having a rim or flange thereabout of different shape or dimensions, which heretofore has necessitated additional patterns for the manufacture thereof.

The object of my invention is to provide meanswvhereby tubs having rims or flanges of any desired shape or dimensions may be made as desired from one or the same pattern with but little cost or labor.

'In the accompanyingdrawings I have shown forms of pattern embodying my improvements, in which- Figure 1 is a plan view of the core-forming pattern in full; Fig. 2, a transverse sectional view through the same on line X X; Fig. 3, an enlarged portion .of 'a transverse sectional View of the same. Fig. 4 is an enlarged transverse sectional view of a portion of the cheekpattern to which the invention also applies.

In practice the core-forming pattern 1,

which in this case I have shown of simple form I as an illustration, is provided all the way about its flange or rim forming edge with a seat, groove, or recess 0, into which is fitted either as one piece or several pieces a suitable flange or outer rim forming piece 2, which rim or flange piece or pieces are held in place by dowel-pins 3 or other suitable means capable of holding the same until a change is desired. The cheek-pattern 1 (which is not shown in full, but of. somewhat similar form to that of the core-pattern) is likewise provided with a groove 0, into which is secured by pins 3' a hollow rim-piece 2/ for forming the under side of the tub-rim in the mold, which rim-piece maybe made of several parts, as in the case of the core-forming pattern.

Should it occur that the rim or flange on the tub to be cast be of less width than the seat or groove into which it is fitted, a filling at and 4, of soft metal or other material, is placed into the space between said flange-forming pieces and groove wall, as shown. It is evident that the rim or flange piece or pieces of either pattern may, if desired, be applied to the member without the necessity of forming the groove or offset in the edge thereof to receive same or that said groove may be of any form. Therefore I do not desire to confine myself to the use of form of said groove as a necessary part of my invention. It is to be understood that the said rim-forming piece or pieces, while detachable from the patterns, are not intended to be detached in the mold when drawing the same, but remain permanently a part of the pattern and are only detached when a change of form is desired.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the patterns for forming sand molds for bath-tubs, of means to permit changing the form and dimensions of the rim or flange thereabout, comprehending a groove or oflset formed around the edges of both patterns, a flange arranged and secured in the groove of each of said patterns composed of one or more pieces, and a filling between the edge of said flange and shoulder of said groove, said flanges adapted to be removed and others substituted.

2. The combination with the pattern for forming sand molds for bath-tubs, of means to said groove, said flange and filling adapted to permit changing the form and dimensions of be removed and others substituted. I0 the rim or flange thereabout, comprehending In testimony whereof I aflix my signature in a groove or offset formed around the edges of presence of two Witnesses. 5 both patterns, a flange arranged and secured FREDERICK D. COOK.
